I recently did the 15K service myself and wanted to share what I have learned for others to see what's involved and maybe inspire other do it yourselfer's out there.
I'm not a Ducati mechanic just a motorcycle enthusiast who likes the satisfaction of working on my own bikes and saving money
My resources for this project were the official Ducati workshop manuel, Ducati Desmoquattro Maintenance & Modification Guide and CA Cycle Works.
Below is the PhotoBucket link to how I successfully checked & adjusted my valves.
Hope you enjoy.
